Make your own pest repellent:
Put 6 cloves of garlic, half an onion, 1 tablespoon of cayenne pepper, and 1 tablespoon of Tabasco sauce in a blender with 1-2 cups of water. Blend until smooth. Mix with 1 tablespoon dishwasher liquid and 1 quart water. Let sit for a day, then strain into a spray bottle to spritz on your plants.
This mixture helps keep insects away and may even help thwart rabbits and raccoons.
